Abstract: Disclosed herein is a plasma treatment method comprising: providing a plasma source and a screen comprising a hydrogel and positioning the screen between the plasma source and a surface of a target to be treated with the plasma such that substantially all of the plasma from the plasma source passes through the screen prior to contacting the surface of the target and the screen reduces the concentration of one or more species from the plasma; and/or contacting a surface of a target to be treated with the gel composition comprising a gel forming material and a liquid phase comprising plasma activated liquid.

Abstract: There is described herein, a plasma device for the generation of oxygen and nitrogen species (RONS) and methods of generating RONS using the plasma device.

Abstract: The present disclosure relates to methods and products for delivering cells to a biological site. Certain embodiments of the present disclosure provide a method of delivering cells to a biological site. The method comprises providing a product comprising an alkylamine functionalised substrate and cells for delivery to the biological site attached to the functionalised substrate, wherein the alkylamine functionalised substrate comprises a surface density with an atomic ratio of primary amine to carbon of greater than 0.005, and applying the product to the biological site to allow transfer of the cells from the product to the biological site, thereby delivering cells to the site.
